Description

Technical Field

[0001] This utility model belongs to the field of nylon fabric edge cutting technology, and relates to an edge cutting device for polyester fabric production. Background Technology

[0002] In the weaving or composite process of polyester fabric, irregular fiber burrs and frayed edges are easily generated. At this time, it is necessary to use an edge trimming machine to trim the polyester fabric. Existing polyester fabric edge trimming equipment generally adopts a working mode of simultaneous edge trimming with double-sided blades. However, there are significant technical problems in actual production. Due to the different requirements of different factories for the edge trimming size of polyester fabric, the adjustment of the double blade spacing of traditional edge trimming machines has obvious limitations. Specifically, the blade positioning mechanism adopts a fixed design. When it is necessary to adjust the cutting width, the operator must complete the spacing adjustment through complex procedures such as manual disassembly, repositioning, and tightening bolts. This mechanical adjustment method is not only time-consuming and labor-intensive, but also leads to frequent production line shutdowns. Utility Model Content

[0003] The technical problem this utility model aims to solve is that existing polyester fabric edge cutting equipment generally adopts a working mode of simultaneous edge cutting with double-sided blades. However, there are significant technical problems in actual production. Due to the different requirements of different factories for polyester fabric edge cutting dimensions, the adjustment of the double blade spacing of traditional edge cutting machines has obvious limitations. Specifically, the blade positioning mechanism adopts a fixed design. When it is necessary to adjust the cutting width, the operator must complete the spacing adjustment through complex procedures such as manual disassembly, repositioning, and tightening bolts. This mechanical adjustment method is not only time-consuming and labor-intensive, but also leads to frequent shutdowns of the production line.

[0004] The present invention discloses a cutting device for polyester fabric production, comprising a support plate, four support feet evenly distributed at the four corners of the lower part of the support plate, a cutting assembly located in the middle of the upper part of the support plate, a cutting release wheel located on the left side of the upper part of the support plate, and a cutting collection wheel located on the right side of the upper part of the support plate.

[0005] The cutting assembly includes two fixed plates, the lower part of each fixed plate is fixedly connected to the front and rear sides of the upper part of the support plate, a first motor is provided at the bottom of the front side of one of the fixed plates, the output shaft of the first motor rotates through the fixed plate, a first rotating shaft is fixedly connected to the output shaft of the first motor, and the rear side of the first rotating shaft rotates through the other support plate, and a second rotating shaft is movably connected to the upper rear side of one of the support plates through a rotating joint, and the second rotating shaft passes through the other support plate.

[0006] The rear ends of the first and second rotating shafts are respectively fixedly connected with gears, and the gears are meshed with each other. Guide strips are fixedly connected to the front and rear sides of the first and second rotating shafts respectively. Cutting wheels are respectively provided on the front and rear sides of the first and second rotating shafts, and guide grooves are respectively opened in the inner cavity of each cutting wheel.

[0007] The guide groove and the guide strip are slidably connected and cooperate with each other.

[0008] Each of the cutting wheels has a limiting wheel rollingly connected to its inner wall on the front and back sides. The inner cavity of the limiting wheel is movably connected to an L-shaped rod through a bearing. Fixed rings are provided on both sides of the cutting wheel. The L-shaped rod is fixedly connected to the inner cavity of the fixed ring. A frame is connected to the upper part of the fixed ring.

[0009] A second motor is fixedly connected to the upper front side of one of the support plates. The output shaft of the second motor rotates through the support plate. A bidirectional lead screw is fixedly connected to the output shaft of the second motor. The rear side of the bidirectional lead screw is movably connected to another support plate through a rotating joint. The inner cavity of the frame is threadedly connected to the bidirectional lead screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the second motor drives the bidirectional lead screw to rotate, and the bidirectional lead screw drives the two sets of frames to produce opposite or backward displacement. The frame displacement drives the four-bar linkage composed of the fixed ring and the L-shaped rod, which forces the limit wheel to advance the cutting wheel along the cutting wheel axis and make linear displacement under the constraint of the guide bar. The distance between the two cutting wheels can be adjusted, and the distance between the cutting wheels can be adjusted without the operator having to manually disassemble it, thereby reducing the workload of the workers.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1

[0021] like Figures 1-5 As shown, it includes a support plate 1, four support feet 2 are evenly distributed at the four corners of the lower part of the support plate 1, a cutting assembly is provided in the middle of the upper part of the support plate 1, a cutting release wheel 3 is provided on the left side of the upper part of the support plate 1, and a cutting collection wheel 4 is provided on the right side of the upper part of the support plate 1.

[0022] The cutting assembly includes two fixing plates 5. The lower part of each fixing plate 5 is fixedly connected to the front and rear sides of the upper part of the support plate 1. A first motor 6 is provided at the bottom of the front side of one of the fixing plates 5. The output shaft of the first motor 6 rotates through the fixing plate 5. A first rotating shaft 7 is fixedly connected to the output shaft of the first motor 6. The rear side of the first rotating shaft 7 rotates through the other support plate 1. A second rotating shaft 8 is movably connected to the upper rear side of one of the support plates 1 through a rotating joint. The second rotating shaft 8 passes through the other support plate 1.

[0023] The rear ends of the first rotating shaft 7 and the second rotating shaft 8 are respectively fixedly connected to gears 9, and the gears 9 are meshed with each other. Guide strips 10 are respectively fixedly connected to the front and rear sides of the surface of the first rotating shaft 7 and the second rotating shaft 8. Cutting wheels 11 are respectively provided on the front and rear sides of the first rotating shaft 7 and the second rotating shaft 8, and guide grooves are respectively opened in the inner cavity of each cutting wheel 11.

[0024] The guide groove and the guide bar 10 are slidably connected and cooperate with each other. The direction of movement of the cutting wheel 11 is limited by the guide bar 10 and the guide groove, so that it can only maintain linear movement.

[0025] During operation: When it is necessary to trim the polyester fabric, the worker puts the polyester fabric to be trimmed onto the cutting feed wheel 3, passes the polyester fabric through the cutting assembly, and then wraps the other side of the polyester fabric around the cutting feed wheel 4. The first motor 6 is started, which drives the first rotating shaft 7 to rotate. The rotation of the first rotating shaft 7 synchronously drives one of the gears 9 to rotate, and then one of the gears 9 drives another gear 9 to rotate, and then the other gear 9 drives the second rotating shaft 8 to rotate. When the first rotating shaft 7 and the second rotating shaft 8 rotate, they can synchronously drive the two cutting wheels 11 to rotate. The two cutting wheels 11 then cut the polyester fabric to be trimmed. After the cutting is completed, the polyester fabric will be wrapped around the cutting feed wheel 4 for storage.

[0026] Example 2

[0027] like Figures 3-5 As shown, the front and rear sides of the inner wall of each cutting wheel 11 are respectively connected to a limiting wheel 12. The inner cavity of the limiting wheel 12 is movably connected to an L-shaped rod 13 through a bearing. Fixed rings 14 are provided on both sides of the cutting wheel 11. The L-shaped rod 13 is fixedly connected to the inner cavity of the fixed ring 14. A frame 15 is connected to the upper part of the fixed ring 14.

[0028] A second motor 16 is fixedly connected to the upper front side of one of the support plates 1. The output shaft of the second motor 16 rotates through the support plate 1. A bidirectional lead screw 17 is fixedly connected to the output shaft of the second motor 16. The rear side of the bidirectional lead screw 17 is movably connected to another support plate 1 through a rotating joint. The inner cavity of the frame 15 is threadedly connected to the bidirectional lead screw 17.

[0029] During operation, the second motor 16 is started to drive the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 drives the two sets of frames 15 to produce opposite or backward displacement. The displacement of the frames 15 drives the four-bar linkage composed of the fixed ring 14 and the L-shaped rod 13, which forces the limiting wheel 12 to advance the cutting wheel 11 along the axis of the cutting wheel 11. Under the constraint of the guide bar 10, the cutting wheel 11 makes a linear displacement, thereby adjusting the distance between the two cutting wheels 11.

[0030] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
